Your response makes it all about me, but I specifically mentioned other people being surprised by their own memorization capabilities after I asked them to consider that maybe they're more capable of memorizing numbers than they believed.
Your comment also says that I memorize through "no effort" when I stated, "almost no effort" which is > "no effort". When I originally memorized pi to 50 digits it took about 15 minutes which is what I could consider "almost no effort" but that's more than 15 seconds which is what I would consider "no effort".
And I'm sorry my comment made you resentful. Hopefully you don't resent other people telling you how with little effort they were able to increase their vertical jump or learn how to play the guitar.
